Application filed January 31, 1905. Serial No. 243,469.

To all whont it may concern:

Be it known that I, JOHN ALEXANDER WVATT, of the city of Halifax,Province of Nova Scotia, Dominion of Canada, have invented certain newand useful Improvements in Carts; and I do hereby declare that thefollowing is a full, clear, and exact description of the same.

My invention relates particularly to dumpcarts, although some of thefeatures thereof cim be applied with advantage to other vehi- 0 es.

The invention relates particularly to the spring mechanism and may besaid briefly to consist of the combination of an axle having verticalperforations, of a pair of pins carried by the cart-body and projectinginto the perforations, and a yielding resistance device between thevehicle-body and the axle. For full comprehension, however, of theinvention reference must be had to the accompanying drawings, forming apart of this specification, in which like symbols indicate the sameparts, and wherein Figure 1 is a front view of a dump-cart provided withmy invention, and Fig. 2 is a longitudinal vertical sectional viewthereof.

The body of the cart is connected to the axle by a pair of pins gcarried by such body and projecting through holes h in the axle, inwhich they are slidably located.

A pair of bearing-plates 7c are secured upon the bottom of thecart-body, one at each side thereof. They are longitudinally slotted, asat 1, and perforated to allow the passage therethrough of the pins 9 Apair of bowsprings m, also perforated to allow the passage therethroughof the pins 9 are located between the bearing-plates and the axle, andthey have slots 12, formed therein by having portions 0 struck uptherefrom. These struck-up portions constitute tongues which projectinto the slots in the bearing-plates, thereby localizing the springs andbearingplates relatively to-one another, while the displacement of thesprings is furthur controlled by bolts 7, projecting through the slotsin the springs and secured in the. cart-body. A pair of expansiblehelical springs s encircle the pins 9 and bear between thebearing-plates and the bow-springs.

What I claim is as follows:

1. The combination with the body portion of a vehicle and an axle havingvertical perforations, of a air of pins carried by the vehicle-body anprojecting into the perforations, and a yieldin resistance devicebetween the vehicle-bo y and the axle.

2. The combination with the body portion of a vehicle and an axle havinga pair of vertical perforations, of a pair of pins carried by the bodyand projecting into the perforations, a pair of bearing-plates upon theunder side of the body one adjacent to each pin, a pair of bow-springshaving their ends bearing slidably upon the bearing-plates and theirconvex sides in contact with the axle, and a pair of expansible helicalsprings bearing between the bearing-plates and the convex sides of thebow-springs.

3. The combination with the body portion of a vehicle and an axle havinga pair of vertical perforations, of a pair of pins carried by the bodyand projecting into the perforations, a pair of slotted bearing-platesupon the under side of the body one adjacent to each pin, a pair ofbow-springs having their ends bearing slidably upon the bearing-platesand their convex sides in contact with the axle, lugs carried by thebow-springs and having their ends located slidably in the slots in thebearing-plates and a pair of expansible helical sprin s bearing betweenthe bearing-plates and the convex sides of the bow-springs.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN ALEXANDER WATT.
